Added value of EUS-B-FNA to bronchoscopy and EBUS-TBNA in diagnosing and staging of lung cancer.

Background: Bronchoscopy and EBUS are standard procedures in lung cancer work-up but have low diagnostic yield in lesions outside the central airways and hilar/mediastinal lymph nodes. Growing evidence on introducing the EBUS endoscope into the oesophagus (EUS-B) in the same session as bronchoscopy/EBUS gives access to new anatomical areas that can be safely biopsied.

Objective: To summarize the current evidence of the added value of EUS-B-FNA to bronchoscopy and EBUS-TBNA in lung cancer work-up.

Virtual reality intervention to improve quality of care during colonoscopy: a hybrid type 1 randomized controlled trial.

Background And Aims: Effective management of patients' pain, anxiety, and discomfort during colonoscopy is crucial for successful completion of the procedure, patient adherence to follow-up examinations, and patient satisfaction. Virtual reality (VR) interventions, as a nonpharmacologic and innovative solution, have demonstrated promising results in managing these outcomes. Nevertheless, there is limited evidence on their effectiveness and implementation.

EUS-guided biopsies versus surgical specimens for establishing patient-derived pancreatic cancer organoids: a systematic review and meta-analysis.

Background And Aims: Patient-derived tumor organoids (PDTOs) are a promising new disease model in pancreatic cancer for use in personalized medicine. However, the overall success rate (SR) of establishing these cultures from EUS-guided biopsies is unknown.

Methods: We searched relevant database publications reporting SRs of PDTO establishment from pancreatic cancer.

The clinical role of remimazolam: Protocol for a scoping review.

Background: Remimazolam, a novel benzodiazepine, shows promise as an alternative to traditional sedatives and hypnotic agents in procedural sedation and general anaesthesia. While preliminary research indicates potential advantages over conventional agents, such as faster onset, predictable duration, and improved safety profile, the extent and quality of existing evidence remain unclear. This scoping review aims to investigate the current clinical role of remimazolam and provide a broad and comprehensive overview.

Using the Endoscope for Endobronchial Ultrasound in the Esophagus.

EUS-B is a procedure using the echoendobronchoscope in the esophagus and stomach. The procedure is a minimally invasive, safe, and feasible approach that pulmonologists can use to visualize and biopsy structures adjacent to the esophagus and stomach. EUS-B gives access to many structures of which some may also be reached by EBUS (mediastinal lymph nodes, lung or pleural tumors, pericardial fluid) while others cannot be reached such as retroperitoneal lymph nodes, ascites, and lesions in the liver, pancreas or left adrenal gland.

Virtual reality interventions to reduce psychological distress during colonoscopy: a rapid review.

Introduction: Colonoscopy can cause psychological distress in patients, consequently discouraging patients from undergoing an unpleasant procedure or reducing compliance with follow-up examinations. This rapid review aimed to assess the feasibility and efficacy of Virtual Reality (VR) interventions during colonoscopy on patients' perceived psychological distress and procedure satisfaction.

Areas Covered: We searched PubMed, CINAHL, ProQuest/All Databases, and Cochrane Library databases on 1 December 2022, with a date limiter of 2002-2022 for articles that investigated the effect and feasibility of any type of immersive VR-based intervention on patients' pain, anxiety, discomfort, and procedure satisfaction immediately before, during, and/or post-procedure of colonoscopy.

Performance of EUS-FNA and EUS-B-FNA for the diagnosis of left adrenal glands metastases in patients with lung cancer: A systematic review and meta-analysis.

Objectives: For diagnosing left adrenal gland metastasis in lung cancer, clinical guidelines recommend to perform EUS, but EUS-B (EUS using an EBUS-scope) is increasingly being used. We evaluated the diagnostic performance of both procedures.

Materials And Methods: We did a systematic review (PROSPERO, CRD42023416205) and searched MEDLINE and EMBASE on 04-July-2023 for studies evaluating EUS and/or EUS-B in diagnosing left adrenal gland metastases in adults with (suspected) lung cancer.

Tissue amount and diagnostic yield of a novel franseen EUS-FNB and a standard EUS-FNA needle-A randomized controlled study in solid pancreatic lesions.

Background And Objectives: Several types of needles are available for EUS-guided tissue sampling of pancreatic lesions. Whereas fine-needle aspiration (FNA) needles typically provide cytological samples, fine-needle biopsy (FNB) needles are designed to obtain microcores with preserved tissue architecture. The aim of this study was to compare tissue amount and diagnostic yield between a modified Franseen-type FNB needle (TopGain; Medi-Globe GmbH, Grassau, Germany) and a standard FNA needle.

Validation of a Novel EUS-FNB-Derived Organoid Co-Culture System for Drug Screening in Patients with Pancreatic Cancer.

Cancer-associated fibroblasts (CAFs) have been shown to impact the chemosensitivity of patient-derived tumor organoids (PDTOs). However, the published literature comparing PDTO response to clinical outcome does not include CAFs in the models. Here, a co-culture model was created using PDTOs and CAFs derived from endoscopic ultrasound-guided fine-needle biopsies (EUS-FNBs) for potential use in drug screening applications.

This case report describes the first Danish case of endoluminal radiofrequency ablation (RFA) of malignant biliary obstruction due to a Klatskin tumour in a 59-year-old male undergoing neoadjuvant therapy. The treatment was interrupted several times due to recurrent occlusions of the bile duct stents. The patient was offered endoluminal RFA of the central bile ducts in order to reduce his tumour burden and possibly achieve longer stent patency, so the palliative therapy could be resumed.

Endoscopic Ultrasound-guided Radiofrequency Ablation Versus Surgical Resection for Treatment of Pancreatic Insulinoma.

Background & Aims: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is emerging as a safe and effective treatment for pancreatic neuroendocrine tumors. We aimed to compare EUS-RFA and surgical resection for the treatment of pancreatic insulinoma (PI).

Methods: Patients with sporadic PI who underwent EUS-RFA at 23 centers or surgical resection at 8 high-volume pancreatic surgery institutions between 2014 and 2022 were retrospectively identified and outcomes compared using a propensity-matching analysis.

Historical perspective on needle development: From the past to the future.

With the introduction of EUS, endoscopy was no longer limited to luminal indications. However, the method was unable to distinguish malignant from benign lesions. Consequently, needles designed for tissue acquisition under EUS-guidance was designed.

Insulinomas are rare neoplasms which may cause significant symptoms and substantially reduce quality of life. In operable patients, the current treatment is primarily surgery with either enucleation or resection of all or parts of the gland. This treatment is associated with high morbidity and long convalescence.

Assessing Putative Markers of Colorectal Cancer Stem Cells: From Colonoscopy to Gene Expression Profiling.

Cancer stem cells (CSCs) are proposed to be involved in colorectal cancer (CRC) initiation, growth, and metastasis. The aim of our pilot study was to assess possible correlations between the clinicopathological characteristics of CRC patients and CSCs gene expression patterns, in order to provide insight into new methods for patient stratification and targeted therapeutic strategies. Our study involved 60 CRC patients, and the following three specific CSC genes were targeted: PROM1/CD133, ALCAM/CD166 and HCAM /CD44.

COLAR: open-label clinical study of IL-6 blockade with tocilizumab for the treatment of immune checkpoint inhibitor-induced colitis and arthritis.

Background: Immune-related adverse events due to immune checkpoint inhibitors (ICIs) are not always effectively treated using glucocorticoids and it may negatively affect the antitumor efficacy of ICIs. Interventional studies of alternatives to glucocorticoids are lacking. We examined whether interleukin-6 blockade by tocilizumab reduced ICI-induced colitis and arthritis.

National clinical practice guidelines for the treatment of symptomatic gallstone disease: 2021 recommendations from the Danish Surgical Society.

Predictors of adverse events after endoscopic ultrasound-guided through-the-needle biopsy of pancreatic cysts: a recursive partitioning analysis.

BACKGROUND AND STUDY AIMS : Endoscopic ultrasound-guided through-the-needle biopsy (TTNB) of pancreatic cystic lesions (PCLs) is associated with a non-negligible risk for adverse events (AEs). We aimed to identify the hierarchic interaction among independent predictors for TTNB-related AEs and to generate a prognostic model using recursive partitioning analysis (RPA). PATIENTS AND METHODS : Multicenter retrospective analysis of 506 patients with PCLs who underwent TTNB.

Colonoscope retraction technique and predicting adenoma detection rate: a multicenter study.

Background And Aims: The success of preventing colorectal cancer relies on the expertise of the colonoscopists. Studies suggest that the retraction technique is a powerful indicator of expertise in distinguishing endoscopists with various adenoma detection rates (ADRs). We aimed to develop a retraction technique score and explore the correlation between endoscopists' retraction technique and their ADRs.

EUS-guided biopsy confocal laser endomicroscopy in patients with pancreatic cystic lesions: A systematic review and meta-analysis.

Background And Objectives: Pancreatic cystic lesions (PCLs) are frequent incidental findings on cross-sectional imaging and represent a diagnostic challenge as different kinds of PCLs harbor a dissimilar risk of malignancy. Two diagnostic tools have recently been developed and introduced: through-the-needle biopsy (TTNB) and needle-based confocal laser endomicroscopy (nCLE). The aim of this meta-analysis was to compare the diagnostic yield and performance, as well as the safety profile of the two methods.
